Background:

We (Openshift Pipelines Team) adding multicluster functionality in Tekton/Openshift Pipelines which enables Tekton Pipelines to provide a central user experience for orchestrating PipelineRun across multiple clusters for horizontal scalability.

Current Status:

• Successfully completed POC with upstream Kueue (MultiKueue)

• Identified that upstream Kueue didn't support custom jobs

• Contributed external custom job support to MultiKueue as part of KEP 2349

• Verified multicluster functionality works as expected with OpenShift Pipelines

Current Blocker:

Red Hat Kueue Operator does not yet support the new multicluster features required for OpenShift Pipelines MultiCluster functionality.

Requirements:

Detailed requirements have been documented and shared with Red Hat Kueue Team:

Impact:

The absence of this functionality in Red Hat Kueue Operator is currently blocking OpenShift Pipelines from supporting MultiCluster capabilities.

Next Steps:

• Red Hat Kueue Team has requested creation of an epic for planning purposes

• Need to prioritize implementation of multicluster support in Red Hat Kueue Operator

Dependencies:

• Red Hat Kueue Team implementation timeline
• Upstream Kueue MultiKueue features (already implemented)
